Hardy Weinberg Equilibrium V-Review

Which best describes the Hardy-Weinberg equilibrium? Unless there is some type of evolutionary force acting upon them: ...

• a population's allele an genotype frequencies are always declining

• a population's allele an genotype frequencies are always increasing

• a population's allele an genotype frequencies are constant

• a population's allele an genotype frequencies are always fluctuating

Who were the Hardy Weinberg Equilibrium named after?

• A physicist and a biologist

• Two biologists

• Two chemists

• A mathematician and a physician

Which of the following is NOT an assumption of Hardy Weinberg Equilibrium?

• Random mating

• No genetic drift

• No mutation

• No natural selection

Why is Hardy Weinberg Equilibrium considered unrealistic in nature?

• Populations are always small.

• Mutations never occur.

• Natural selection and other forces are always at play.

• Organisms always mate randomly.

What does the equation p + q = 1 represent in Hardy Weinberg Equilibrium?

• Allele frequencies

• Mutation rates

• Genotype frequencies

• Population size

In the equation p2 + 2pq + q2 = 1, what does 2pq represent?

• Homozygous recessive frequency

• Heterozygous frequency

• Homozygous dominant frequency

• Allele frequency

If q2 = 0.25, what is the value of q?

• 0.75

• 1

• 0.25

• 0.5

Given p = 0.5 and q = 0.5, what is the frequency of the homozygous dominant genotype (p2)?

• 1

• 0.75

• 0.5

• 0.25

What is the frequency of the heterozygous genotype (2pq) if p = 0.5 and q = 0.5?

• 0.75

• 0.25

• 0.5

• 1

What should you always check when you get your final results in Hardy Weinberg calculations?

• That p is greater than q

• That the values add up to 1

• That p equals q

• That q is greater than p
